CEREC CAD/CAM Inlays, Onlays & Crowns Consent and Patient Treatment Explanation Lake Orion Family Dentistry

We’ve created this document so that our patients have a better understanding about the steps involved in restorative dental treatment. Please feel free to ask any questions concerning your proposed treatment. The better informed our patients are, the more efficient the treatment is. Communication is the key to success!

Explanation A CEREC restoration is a CAD/CAM (computer aided design & manufacturing) that is custom made for the patient right here in our office. . The advantages are numerous including:  One visit dental restorations which saves the patients time just in travel time alone An extremely strong and natural looking restoration that should last many years Only one ”shot“ of anesthetic.  No ”temporary“ restoration An inlay or onlay is a restoration that partially covers and protects a tooth that has been damaged by:  Decay (a bacterial infection)  A large filling that should not be replaced with another filling to avoid future problems Fracture/breakage of part of the tooth due to trauma, previous decay, unsupported previous fillings, or biting into a very hard object . This is a very conservative way to repair only the bad part of the tooth and not take anymore tooth structure away then we have to. A crown is a similar restorative device to fully or partially cover and protect a tooth that has been damaged by:  Decay (a bacterial infection)  A large filling that should not be replaced with another filling to avoid future problems A bigger fracture/breakage of part of the tooth due to trauma, previous decay, unsupported previous fillings, or biting into a very hard object that cannot be partially covered due to the amount of tooth structure that’s missing A crown build up (or core) is a large restoration to replace the missing portion of the damaged tooth so that the crown or bridge has some structure to be supported and bonded to. . The crown build up materials that we use are similar to our bonded restorations so that they:  ”Seals“ up the small sensitive tubules that lead from the outside of the tooth to the nerve chamber, decreasing hot and cold sensitivity.  Are less hot and cold sensitive because they are not metal but reinforced plastic-type materials. They physically and chemically bond to the tooth structure to strengthen the tooth and the crown or bridge to the tooth.  Treatment Sequence . It takes only one appointment to restore your tooth with a CEREC crown/inlay/onlay restoration.  That is because the restoration is custom crafted with our CAD/CAM system right here in the office  First visit  We start with a digital x-ray of the tooth to make sure that no infection is at the end of the root before with construct the crown. Sometimes abscesses are in the tooth and the patient doesn’t even know it. We, of course, will thoroughly "numb" you up with local anesthetic to make you comfortable.  We then remove any restorative material, decay, chalky demineralized tooth so that we are at sound tooth structure The crown build up or core, if required, is next and is bonded physically and chemically to the tooth This material strengthens the tooth, decreases sensitivity, and releases fluoride into the area to decrease the chance of new decay under the crown  The tooth is then shaped so that the restoration fits over/in/around the remaining tooth  Often we use medicine impregnated string to gently push the gums away from the tooth so that the 3D infrared camera can see where the restoration will intersect with the tooth An optical final impression of the prepared tooth is taken next Therestoration is then designed on the computer and this information is sent digitally to the milling unit in our in house dental lab. That same day we bond the restoration in your mouth with composite bonding technology. Options The options for a CEREC crown/onlay/inlay are: . To do nothing (not a very good idea!). You may possibly require a root canal or extraction is the tooth decays and/or fractures further. . Fix the tooth with just a crown build up. The tooth may still eventually break There has to be enough tooth structure to hold the buildup in place and keep the tooth from breaking when you chew . Extract the tooth and place either a bridge or single/multiple dental implants Replacing an extracted tooth is much more of an investment then restoring the tooth the correct way the first time!  Dental implants surgically replace the missing tooth root for an extracted tooth and allow us to place a replacement tooth without the need for a bridge. Ask us if you have more questions about the differences! Overall risks of CEEC crown/onlay/inlay placement There is about an 8-10% chance that the tooth could require a root canal . A "root canal" is a procedure for preserving infected teeth that would otherwise be extracted. . The tooth, of course, had previous damage. Otherwise we would not be restoring it with a crown  Sometimes the damage is so bad that the nerve/blood vessels inside the teeth become infected and that’s where a root canal comes in . This is where the blood vessels and nerves coming from the jawbone are and the source of the intense pain and pressure that a patient may experience. . Once the Doctor locates the nerve chambers (root canals), we place tiny files into each of them. With filing we clean out the infected remains and prior to the root canal filling material placed, the root canals are sterilized .Root canal therapy is about 90-95% successful. .The fee for the Root Canal Treatment does not include any type of restoration needed to properly restore the tooth fully .Teeth treated with root canals/crowns/onlays/inlays can still decay, but since the Doctor removed the nerve, there will probably be no pain.

There is a chance the CEREC crown/onlay/inlay could fracture  A CEREC crown/onlay/inlay is very strong but just like your own teeth they can fracture and develop new decay too. The materials don’t decay but the teeth themselves can redecay due to immune system problems/lack of home/lack of professional care.  A CEREC crown/onlay/inlay are made out of a solid block of ideally manufactured porcelain are proven by over 20 years of clinical research to last many years

The nature of restorative CEREC crown/onlay/inlay treatment and sequence has been explained to me and I have had a chance to have my questions answered. In light of the above information, I authorize the Doctor to proceed with restorative treatment.

I acknowledge that I have received a copy of this consent form.
